EYEGLASSES.

Application filed May 18, 1912. Serial No. 698,239.

To all whom it may concern:

Be it known that I, FREDERICK L. ALLEN, a citizen of the United States,residing at Boise, in the county of Ada and State of Idaho, haveinvented new and useful Improvements in Eyeglasses, of whichthefollowing is a specification.

This invention relates to eye-glasses, the object in view being toprovide an eflicient and reliable connection between the nose piece orframe and the lenses, whereby the lenses may be securely connected tothe frame, and all lost motion thereof prevented, the fastening deviceserving by reason of its construction to take up the slight wear whichis caused by constant use of the glasses, and at the same time enablingthe lenses to be readily detachedfrom the .frame or nose piece whenrequired.

With the above and other objects in view, the invention consists in theconstruction, combination and arrangement of parts, as will behereinafter more fully described, illust ated in the accompanyingdrawings, and pointed out in the claimshereunto appended.

In the drawings: Figure 1 is a rear'ele ration of a pair of eye-glasses,embodying the present invention. Fig. 2 is a front elevation of thesame. Fig. 3 is a longitudinal section taken through the point ofconnection between one of the lenses and the nose piece or frame. Fig. 4is a cross section taken atright angles to Fig. 3. Fig. 5 is a detailperspective View of the 'joint between a lens and the nose piece.

Referring to the drawings, 1 designates a nose piece or frame, theopposite extremities of which are bifurcated or forked, as shown at 2.To each of the branches of the fork 2, there is coimectcd rigidly a postor pin 3. These two posts extend. in parallel relation to each otherthrough holes 4 in the adjacent margin of the lens 5, and each of saidposts or-pins is provided with a longitudinal slot 6.

7 designates a lock or fastener, consisting of a piece of spring wire ofsuitable length, bent into the form of a loop, as shown, so that thecentral portion of the loop may pass over and embrace the nose piecejust back of the fork above described.

The parallel portions of the loop are bent' intermediate the bight toextend around the edge of the lens and form spring arms 8, theextremities of which are bent outwardly in opposite directions toscription and by reference to the drawings,

that the spring arms of the fastener serve to force the wedge-shapedterminals thereof into the slots of the posts or pins, and at the sametime they bear against the lens, thereby pushing the lens firmly againstthe branches or arms of the fork. This prevents any possibility of thefastener or the lens working loose, keeps the lens in close contact withthe fork, and takes up any wear which may be caused by constant use ofthe glasses.

What is claimed is:

l. A nose piece for eye-glasses having a bifurcated extremity, parallelposts extending therefrom and provided with longitudinal slots,- and alock in the form of a loop of wire embracing the nose piece and havingoppositely projecting extremities entering the slots in the posts.

2. A nose piece for eye-glasses having a bifurcated extremity, parallelposts extending therefrom and provided with longitudinal slots, and alock in the form of a loop of spring wire embracing the nose piece andhaving oppositely projecting extremities cutering the slots in theposts.

3. A nose piece for eye-glasses having a bifurcated extremity, parallelposts extending therefrom and provided with'longitudinal slots, and alock in the form of a loop, I

embodying spring arms, the said loop cinhi acing the .nose piece andhaving oppositely projecting extremities entering the slots in theposts.

4. A nose piece for eye-glasses having a bifurcated extremity, parallelposts extending therefrom and provided with longitudinal slots, and alock in the form of a loop of spring wire, embracing the nose piece andhaving oppositely projecting and wedgeshaped extremities entering theslots in the posts.

In testimony whereof I aliix my signature in presence of two witnesses.

FREDERICK L. ALLEN.
